HENRY DAWSON FURNISS, OF NEW YORK, N. Y.

OILING- SYSTEM.

To all whom it may concern Be it known that I, HENRY DAWSON FURNISS, ofNew York, in the county of New York, and in the State of New York, haveinvented a certain new and useful Improvement in Oling Systems, and dohereby decla-re that the following is a full, clear, and exactdescription thereof.

My invention relates particularly to systems used for oiling journalsand similar parts of mechanical constructions requiring oiling. Myinvention is particularly app-licable, however, to the oiling ofjournals and journal bearings upon railway trucks and similar'constructions in which an absorbent body, such for example as cottonwaste, is used to assist in applying the lubricating medium.

It is a well-known fact that many railway accidents occur because of thefailure of the oiling devices to adequately lubricate the journals andjournal bearings on railway trucks. This results in the production ofheated axles and bearings,the eifect of which has frequently been tobring about serious accidents.

The object of my invention is to provide an oiling system which willavoid the dangers incident to imperfect oiling, which will require muchless care and attention and which will maintain a proper lubrication ofthe parts to be oiled for longer periods of time without reiilling. Myinvention is of great importance in the operation of ordinary railroadtrains for the reasons indicated, but it is particularly useful,however', in the operation of trains at high speeds and with few stops.

While my invention is capable of embodiment in many different forms, forthe purpose of illustration I have shown only one form in theaccompanying drawings, in which the figure is a vertical section of anoiling system constructed in accordance with my invention.

In the drawings I have shown a truck 1 for a railway coach, the samehaving journal bearings 2 supported upon an axle 3, passing through acar wheel 4; of the usual construction. The end of the axle 3 projectsinto an oil box 5, having an inclined hinged lid G of the usual kind. Atsome distance above the bottom of the oil box 5 I provide a perforatedplate or wire gauze 7 to support above the same a body of absorbent 8,`such for example, as cotton waste. Extending down to Specification ofLetters Patent.

Serial No. 767,527.

and preferably connected to the perforated plate, there is a pipe 9having its sides cut out to produce lateral openings lO. The perforatedplate l0 is entirely open immediately beneath the end of the pipe 9 toprovide an entirely free passage for the supply of oil from the pipe 9to the part of the oil box beneath the perforated plate. The pipe 9 isprovided with a stop cock 10L to be closed when the oilingsystem isbeing reiilled with oil. The pipe 9, at its upper end, leads into an oilsupply chamber 11, constructed preferably upon the top of the oilingbox. The oil supply chamber is provided with a hinged cover 12 whichmakes an air tight joint with the top of the oil supply chamber throughthe presence of a gasket 12 of rubber, or any other suitable material.In order to hold the cover' 12 in place a hinged bolt l2", with a thumbnut 12C, is provided, extending through a slot 1Q in the edge of thecover. It is to be understood, however, that the oil supply chamber 11may supply any number of oil boxes with oil.

In the operation of the oiling system a quantity of oil of the kindordinarily used for oiling railway truck journals is poured into the oilsupply chamber 11, the stop cock l0 having been previously closed untilthe filling operation is completed. The lid 12 is then secured in placeand the stop cock 10n is opened. The oil will now flow downwardlythrough the pipe 9 until the oil reaches the level of the uppermostportion of the lateral openings 10. A level of oil will thus beestablished somewhat above the level of the perforated plate 7. By thismeans the absorbent 8 will be constantly maintained in a body of oil ofeven depth. At the same time there will be present a large body of oilbeneath the perforated plate, and, therefore, beneath the body ofabsorbent which will immediately supply a large quantity of oil to thebottom of the body of absorbent material so as to maintain the lowerportion of the body of waste invariably and at all times in a body ofoil. In case the oil located above the perforated plate is rapidly usedup, as for example, by heating of the axle and journal boxes the largebody of oil below the perforated plate immediately passes through theperforated plate at a rapid rate, thereby immediately renewing the levelof oil located above the perforated plate maintaining invariably theconstant feed desired. It will be understood, of course, that as thebody of oil located above the perforated plate passes upwardly, saidbody of oil is replenished by oil passing downwardly from the supplytank l1. A greater flow of oil downwardly through the pipe 9 is possiblewith this construction than in previous constructions,

as the end of the pipe is not in any way,

obstructed by the presence or interposition of absorbent materials, suchas cotton waste. In my system the oil may flow out of the end of thesupply pipe without being obstructed in any way and the actual feed ofthe oil to the cotton waste takes place over an exceedingly largesurface through the many openings in the perforated plate.

While I have described my invention above in detail, I wish it to beunderstood that many changes may be made therein without departing fromthe spirit of my invention.

I claim:

l. In an oiling .system the combination of a body of absorbent material,a perforated support therefor, and means for maintaining a constantlevel of oil therein comprising an oil supply pipe adapted to supply oilbelow the support and having a lateral opening to maintain the level ofthe oil above the support.

2. In an oiling system the combination of a body of absorbent material,a perforated support therefor, and means for maintain- .above thesupport.,

3. In an oiling system the combination of a body of absorbent material,a perforated support therefor, and means for maintaining a constantlevel of oil therein comprising an oil supply pipe connected to thesupport and adapted to supply oil below the support.

4, In an oiling system the combination of a body of absorbent material,a perforated support therefor, and means for maintaining a constantlevel of oil therein comprising an oil supply pipe connected to thesupport and adapted to supply oil through the support.

5. In an oiling system the combination of an oil boX containing a bodyof absorbent, a perforated plate supporting the same, an

oil supply pipe arranged to feed oil below V l the` perforated plate andhaving a lateral opening above the perforated plate, an oil supplychamber connected to the pipe having an air-tight cover and a stop cocklocated in the pipe.

In testimony that I claim the foregoing I `l have hereunto set my hand.
